Alleges that Mr. Dhinakaran, the party’s sidelined leader, had “aligned” with the DMK to topple the “Amma government”, a reference to the the AIADMK government.

An AIADMK MP from the T.T.V. Dhinakaran camp on Friday switched sides to extend support to Tamil NaduChief Minister Edappadi K. Palaniswami in a boost to Mr. Palaniswami's faction.

M. Vasanthi, the AIADMK MP from Tenkasi (SC), alleged that Mr. Dhinakaran, the party’s sidelined leader, had “aligned” with the DMK to topple the “Amma government”, a reference to the the AIADMK government.

“Is it fair for him (Dhinakaran) to say he will topple this government by aligning with the DMK. He has been repeatedly saying that and we don’t like it. The 1.5 crore supporters of the party are agitated over this,” she said when asked about her switching sides.

Speaking to reporters after meeting Mr. Palaniswami here, she said the chief minister and his deputy Mr. O. Panneerselvam will take forward the public work left behind by Jayalalithaa and continue to deliver the various welfare schemes.

“Amma worked selflessly for the people. How can that government be toppled,” she said.

The MP felt that the pro-Dhinakaran MLAs staying at a resort in Coorg in Karnataka had been “imprisoned” and asked if it was fair to do so as they were elected to serve the public.

More persons might switch sides from Mr. Dhinakaran’s camp in the coming days, she said.

While factions led by Mr. Palaniswami and Mr. Panneerselvam had merged on August 21, the very next day, 19 MLAs owing allegiance to Mr. Dhinakaran had met Governor Ch Vidyasagar Rao, saying they had lost confidence in the chief minister.

They had sought his removal. However, one MLA later switched to Mr. Palaniswami’s camp.

Since then, opposition parties including the DMK, besides the Dhinakaran faction, have been demanding that Mr. Rao order a floor test of the Palaniswami government, saying it has “lost majority.”

Speaker Dhanapal had disqualified 18 MLAs on September 18. They have since moved the court against the disqualification.

Mr. Dhinakaran had earlier ruled out any direct or indirect pact with the DMK but has been asserting he will “send home” the Palaniswami government, accusing the chief minister of “betrayal.”

He has been accusing Mr. Palaniswami of “betraying” the now-disqualified party chief V.K. Sasikala, saying she was the one who had nominated him to the top post following a revolt by then-rebel leader Mr. Panneerselvam in February.
